Abstract
El objetivo de este proyecto ha sido realizar el diseño, fabricación y medida de dos antenas de parche planas multifrecuencia de doble y triple banda respectivamente. Entre las ventajas de los parches destacan que son antenas muy ligeras y fáciles de fabricar e integrar en circuitería. Sin embargo, presentan ciertas desventajas como su complejidad a la hora de conseguir que funcionen en múltiples bandas. En este proyecto dicha respuesta multibanda se ha conseguido integrando partículas resonantes metamateriales OCSRRs (Open Complementary Split Ring Resonators) en la propia estructura del parche. De esta manera, se han conseguido antenas operativas para frecuencias próximas entre si, escogidas arbitrariamente, en un único dispositivo plano y monocapa.
Como parte del trabajo efectuado, se han fabricado dos prototipos. El primero de ellos consiste en una antena de parche de doble banda que presenta un diagrama de radiación de tipo parche en cada una de sus bandas. Sin embargo, en el caso de la antena de parche en triple banda cabe destacar que combina diagramas de radiación de tipo parche y monopolar, lo que puede resultar de utilidad para algunos sistemas de comunicaciones.
Finalmente, los contenidos de la presente memoria se han organizado como se indica a continuación. En primer lugar, en el Capítulo 1, se introducen algunos conceptos relativos a los metamateriales y a las antenas de parche. A continuación, en el Capítulo 2, se presenta un estudio previo de la estructura de antena multibanda realizada en el que se combinan antenas de parche con un tipo de partículas metamateriales conocidas como OCSRRs (Open Complementary Split Ring Resonators). En tercer lugar, en los Capítulos 3 y 4 se presentan los principales resultados obtenidos con los dos tipos de antenas implementadas. Por último, en el Capítulo 5, se exponen las principales conclusiones del proyecto así como posibles líneas futuras del mismo.
The goal of this project was to design, manufacture and measure two multifrequency planar patch antennas, with dual-band and tri-band response respectively. On the one hand, patch antennas have certain advantages. For instance, they are lightweight and easy to manufacture and integrate into circuits. On the other hand, they present some drawbacks such as the complexity to make them work in multiple bands. In this project such multiband response was achieved by integrating the so called OCSRR (Open Complementary Split Ring Resonators) metamaterial particles into the structure of the patch. In this way, operating antennas have been achieved for near frequencies, arbitrarily chosen, in a planar monolayer device. As part of the work done, two prototypes were manufactured. The first one consists of a dual band patch antenna with patch-like radiation pattern in both bands. However, the triple band patch antenna combines patch-like and monopolar-like radiation patterns, which may be useful in some communication systems. Finally, the contents of this memory are organized as follows. Firstly, in Chapter 1, some concepts of metamaterials and patch antennas are introduced. Then, in Chapter 2, a previous study of the structure of multi-band antenna on which patch antennas are combined with a type of metamaterial particles called OCSRRs (Open Complementary Split Ring Resonators) is presented. After this, in Chapters 3 and 4, the main results obtained with the two implemented antennas are presented. Finally, in Chapter 5, the main conclusions of the project and possible future lines are exposed.
